Fuel efficiency standards are regulations set by governments to ensure that vehicles use less fuel and produce fewer emissions. These standards require car manufacturers to design their vehicles in a way that maximizes miles per gallon (MPG), which helps reduce the overall environmental impact. By improving fuel efficiency, we can save money on gas and decrease our reliance on fossil fuels. These standards often apply to various types of vehicles, including cars, trucks, and SUVs. They are important for promoting cleaner air and combating climate change. As technology advances, manufacturers are finding innovative ways to meet these standards, such as developing electric vehicles and improving engine designs.
